SADDLE-HUB AND FERRULE COMBINATION.

SPECEFICATION forming part of Letters Patent No. 399,850, dated March 19, 1889.

Application filed December 7, 1887. Serial No. 257,259. (No model.)

To all whom t may concern:

Be it known that I, MARTIN F. DoLAN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in a Combination Saddle-Hub Connection, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, ina which l Figure l is a sectional view of my device. Fig. 2 is a perspective View of the ferrule. Fig. 3 shows the clamp. Fig. 4t is a side view of the saddle-hub, and Fig. 5 shows the jamnut.

The object of my invention is to construct, by combining a saddle-hub and ierrule, a saddle-hub connection that will require but one opening in the main pipe A, into which opening the branch connection is to be made, and through the same opening the saddle-h ub and ferrule are to be attached and securely fastened to the main pipe A. I desire to construct a saddle-hub connection that can be easily and readily disconnected from the main pipe A after it has been securely attached to the saine. I desire also to dispense with the necessity of having to calk with lead the ferrule B into the saddle-hub fi). By combining the ferrule B with the saddle-hub l) it reduces the size oi. saddlef f3, and which reduction of the saddle makes the application of my saddle-hub combination more feasible and convenient to attach to the main pipe A when the space on the main pipe is limited or contracted. l

My saddle-hub combination is intended to be attachable to iron pipe or any metal pipe of a hard composition. It can be used as a connection for water, air, or gas, if desired.

In the sectional view, Fig. l, A is the main pipe with an opening in it, a a2. The opening is circular in form, and is made large enough to admit the lower end of ferrule B and clamp O to be inserted and connected, as shown.

B, Fig. 2, is the ferrule, which is made of cast metal. Brass is preferable. It has on its under side a lug, Z), which is cast on and is part of the ferrule. The lug h is vcircular in form, so as to correspond to the form of the main pipe A on its inside, to which the lug b Fig. 2, to the main pipe A, Fig. l.

stands parallel when attached. At the end of the lug h it is tapering to the edge r. The lug b is for the purpose of attaching the under side of the lower end of tei-rule B to the ina-in pipe A at the opening a', by which the lug b compresses the inside ot the main pipe A along the surfacej, as shown in Fig. 1. On the top part of the lower end of the ferrule B there is cast on and standing up perpemlimilar from the fer-rule a square peg, c. It is for the purpose of connecting the top part ot' the ferrule B to the main pipe A, Fig. l. The

peg c is inserted through the square aperture e in the clamp C, Fig. 3, by which movement the ferrule B, Fig. 2, is connected with the main pipe A, as shown in Fig. 1. On the outer side of the ferrule B, Fig. :2, it has a thread cut, 'L'. The threads 'i are for the purpose of tightening and securely fastening the ferrule B to the main pipe A. By turning to the right the ja1n-nut E, Fig. 5, on the thread of ferrule `z', (when the saddle-hub D is in its place,) it will draw the ferrule B outward from the main pipe A, and which action coinpresses the lug b on the fer-rule B and the lug d on the clamp C, Fig. 53, againstI the inside of the main pipe A at j and o, as shown in Fig. l. On the upper end of f'errule B at z" t2 is where the pipe or branch connection for which the openin g was made is to be attached to the fcrrule B. The ferrule B will be attached to lead pipe by soldering and to iron by calking.

C, Fig. S, is the clamp, which is made of cast metal, (brass.) It has a square aperture, e, and a lug, (l, which stands perpendicular from the clamp part (l. The lug d is circular in form, so as to correspond to the form on the inside of the main pipe A, to which it is attached, and stands parallel on the inside. The lug d is tapering at the end a. The clamp C is for the purpose of connecting the top part of the lower end of the ferrule B,

The aperture e in the clamp O slips over the peg c on the errule B, Fig. 2, and by turning the jamnut E, Fig. 5, on the threads i of fel-rule B, Fig. 2, it draws the ferrule outward from the main pipe A, and which action compresses the lug d against the surface of the inside of the main pipe A at o, as shown in Fig. l.

TOO

D, Fig. 4, is the saddle-hub, which is constructed of east-iron. It has a groove, s, in it on the inside of the hub, and which groove s is made so as to allow the saddle-hub to slide over the clamp C, Fig. 3, when the clamp is attached to the ferrule B. rlhe groove s braces and holds hrm and prevents the clamp C :from slipping oft ot the peg c on the ferrule B, Fig. 2, when the clamp is attached to the ferrule. The saddle f f2 f3 of the hub D compresses the outside of the main pipe A when the jam-nut E, Fig. 5, is tightened on the ferrule B, and it thereby holds iirm and secure the ferrule B when it is attached to the main pipe A, Fig. l. The saddle f fzf3 is concave in form, as it must conform to the convex or outside of the main pipe A, where the pressure must be equalized on the surface of the main pipe A at m m2 when the jamnut E is turned tight. rlhe saddle j" f2 f3 also makes tight and secure the opening in the main pipe A at a. CL2, through which the ferrule B and clamp C are inserted, by applying a thin rubber washer or .a small quantity of putty at the outside edge of the opening d 02, as shown in Fig. l. The pressure of the jam-nutE is on the face ot the saddle-hub D at 7a k.

E, Fig. 5, is the jam-nut. It can be constructed of brass or iron in cast metal. It has six square edges, 7L 7i', on which edges the wrench is to be applied to turn the j ain-nut E on the threads t' of ferrule B when it is desired to attach or detach the connection from the main pipe A. There is an opening, ac, in the jam-nut E, and on the inside surface of the opening or it has a thread cut, n, n, which thread is of the same size and gage as the thread i on the ferrule B, on which the janinut E operates. The jam-nut E is to tighten, secure, and hold .firmly in its place the saddle-hub connection when it is attached to the main pipe A. By applying a wrench on the jam-nut E at 71y 71, and turning' the nut to the right on the thread y of ferrule B it tightens the connection with the main pipe A by drawing the ferrule B outward from the main pipe A, and at the same time it compresses the saddle-hub D inward or against the outside of the main pipe A, and thereby makes a iirm and secure connection, as shown in Fig. l.

The sectional view, Fig. l, shows the saddle-hub and ferrule attached to the main pipe A, and it also shows, by the dotted lines, the connection detached from the main pipe A and the manner of attaching it. A is the main pipe with an opening in it, d d2. By holding the ferrule B on an angle, as shown by dotted lines, I insert the lug I) B, Fig. 2, into the lower part of opening d in the main pipe A. Then taking the clamp C, Fig. i3, and holding it on an upward and oblique angle, I insert the lug d C, Fig. 3, into the top part of the opening d2 in the main pipe A, as shown by dotted lines. Then elevating the ferrule B, Fig. 2, upward, as shownl by arrow,

and lowering the clamp C, Fig. 3, as shown by arrow, the peg c B, Fig. 2, is inserted through the aperture e C, Fig. 3, and thereby connects the ferrule B, Fig. 2, to the main pipe A, Fig. l, the lug b B, Fig. 2, and the lug d C, Fig. 3, standing parallel with the inside of the main pipe A. Move up the saddle-hub D, Fig. al., till the saddle f f2 touches the main pipe A. The groove s in the hub D, Fig. 4, fitting snugly over the clamp C, Fig. f5, holds the clamp C steady on the peg c B, Fig. 2. By turning' the jam-nut E, Fig. 5, on the thread i of ferrule B, Fig. 2, to the right it causes the ferrule B, Fig. 2, to draw outward from the main pipe A, and thereby compresses the lug o B, Fig. 2, and lug d C, Fig. 3, against the inside o'f the main pipe A at o and j and secures the ferrule B, Fig. 2. By the same turning of the jam-nut E, Fig. 5, and simultaneously with I the outward movement of the terrule B, Fig. 2, the saddle-hub D, Fig. 4, is compressed by the jam-nut E, Fig. 5, at 7- r., and therefore compresses the saddlef f2 f3 against the outside of the main pipe A at the surface m m, and thereby making a safe and secure connection, as shown in Fig. l, and it dispenses with the necessity of having to calk with lead the i'errule into the saddle-hub.

The saddle-hub and ferrule combination can be constructed so as to make connections with the main pipe A at any angle from forty-five degrees-thus y to a right angle, thus "Il, as is desired.

I am aware of there being a saddle-hub that requires but one opening to be made 'inthe main pipe A, but which saddle-hub is at tached to the main pipe A by a band of iron, which en circles the main pipe A, and the ends of the band which are threaded are inserted through the hole on each side of the saddle, and the nut is turned tight, which act fastens the saddle-hub to the main pipe A. My manner ot attaching my combination I claim is superior and greatly improved over that way ot attaching to the main pipe.

It is obvious that my device forms a detachable pipe-joint, which is adapted not only for use in connection with gas or water mains, or for the purpose of attaching Ventilatingtubes, but is applicable wherever it is desired to forni a detachable connection with or to tap from the outside any hollow body.

The size, construction, and arrangement of the various parts maybe modified and equivalents substituted therefor.

The ferrule B, which is the technical term used in the trade, consists simply of an ordinary brass pipe of any suitable diameter and thickness.

I claiml. In a detachable pipe-joint applicable from the outside to a hollow body, the combination, with a pipe or ferrule provided with a stationary lug and with a stationary clamp or lug removable for purposes of inserting the ferrule into the hollow body, and with a saddle arranged to encircle the it'errule and to travel IOO IIO

forward on the ferrule and clamp Without turning and to rest against the exterior of the hollow body, of suitable deviees whereby the saddle and the ferrule-lugs may be clamped together' and the Whole rigidly secured to the hollow body, as and for the uses and purpose set forth.

2. The combination, with the pipe or ferrule B, provided With a clamp, C, of the jamnut E and saddlehub D, provided with a groove, s, and adapted to Work back aud forth upon the clamp C of the ferrule or pipe B, substantially as described.

3. The combination, with the jam-nut E, saddle-hub D, and with the pipe or ferrule B, provided with a stationary lug, l), and with a piu, c, of the detachable Clamp C, provided with an aperture, e, adapted to contain the pin o, substantially as set forth.

Ll. The combination, With the pipe or ferrule B, provided with a stationary lug', h, and with the pin c, and also with the detachable Clamp C, provided with a lug, d, and with the aperture e, adapted to Contain the piu c, and also with the saddle-hub D, provided with a groove, s, and adapted to Work ou the clamp C of the ferrule B, of the jam-:nut E, adapted to engage both with the pipe or errule B and the saddle-hub D, and thereby rigidly secure the parts together, substantially as described. 3o
